§
Instalation
The easiest way is to install the debian package (also available
in Ubuntu) using apt-get.

# apt-get install go2

Once it is installed, each user need to include next line at the
end of their ~/.bashrc:
[ -e /usr/lib/go2/go2.sh ] && source /usr/lib/go2/go2.sh
In the next shell session, go2 will be ready to use.

§
Manual
Go2 is very easy to use. From any directory just execute:

$ go2 prefix

when 'prefix' is the beginning of the directory you want to
go. go2 will search in your 'home' and it will list all the
directories that match the prefix.

Each match has a associated letter. To choose the target, just
press the corresponding key. If you want to abort the search,
you may press the ESC key (or C-c). You may choose the first
match pressing ENTER. The selection may occurs in any
moment, it is not required that you wait the searching is
finished.

go2 remembers all the successful searches, so it is faster each
time.

§
Other options

go2 has some options to perform searches from the '/'
directory, to ask case-insensitive matching, etc. Try this:

$ go2 --help
usage: go2 [-h] [--cd] [-i] [-r] [--setup] [--version] [pattern [pattern ...]]
